Penggunaan Model Aktivitas Investigasi Autentik Yang Dimodifikasi Untuk Memahami Konsep Rasio Dan Proporsi

Abstract

Comprehensive understanding on ratio and proportion are still an obstacle for some pre-service teachers, even though ratio and proportion is the cornerstone of advanced mathematics. Therefore it needs a learning model that can facilitate pre-service teachers in mastering ratios and proportions. Modified Authentic Investigation Activity is able to optimize the ability of pre-service teachers on ratio and proportions. This model with its learning syntax can help pre-service teachers more understand ratios and proportions comprehensively. In addition, this model also provides insight various strategy problem-solving of ratio and proportions that can add repertoire of knowledge of pre-service teachers
